Arvin Gаrrett appeals the dismissal of his second habeas corpus petition by the District Court. 1 The Court dismissed two of his four proffered grounds for relief as successive and two as abusive. We hold that petitioner has not met the requirements necessary to allow us tо consider this successive petition on its merits. Therefore, we affirm.
I.
Arvin Garrett was convicted in 1978 of the first degree murder of James Bundy.
2
Thе Court sentenced him to life imprisonment without possibility of parole for 50 years. After an unsuccessful appeal of the guilty verdict,
State v. Garrett,
Garrett advanced four grounds for relief in his petition tо the District Court. He contended first that his confession was involuntary because of his diminished mental capacity. He also claimed that his conviction was obtained through a violation of his right not *285 to incriminate himself, again because his diminished mental capaсity impeded his ability to recognize his rights. He asserted that the trial court’s failure to sequester the jury and notify him of the nature of the charges violated his equal-protection rights. Finally, he argued that his trial, appellate, and state post-conviction counsel were ineffective. Recognizing that he faced a higher hurdle on his second petition, Garrett offered mental incapacity as an excuse providing the cause that a repeat petitioner must show to avoid having his claim dismissed. He offered tо present as evidence in support of this claim the fact that drugs were being administered to him while in prison to treat his anti-sociаl personalty disorder. 3 Garrett argued that the mental illness prevented him from developing fully the claims he made previously, and frоm realizing the existence of the claims he failed to make.
II.
In general, second or successive petitions for writs of habeas corpus must be dismissed unless the petitioner can show both cause and prejudice — cause, for example, justifying his failure to raise certain claims in an earlier petition, and prejudice resulting from those claims’ not having been raised and decided earlier. See,
e.g., Washington v. Delo,
Even if petitioner’s allegations in thе present ease meet this standard, which we doubt, he cannot succeed, because the state courts have already found him competent, and this finding is entitled to a presumption of .correctness under 28 U.S.C. § 2254(d)(8). Defendant has been contending ever since 1978 that he was suffering from mental infirmity and was being treated with Thorazine and Mellaril. His motion for a mental examination before sentenсing was denied, and this action was affirmed on direct appeal.
State v. Garrett, supra,
We hаve no reason to doubt these findings. They certainly establish that petitioner was competent and able to assist in his own defense at the time of the trial. It appears from papers filed by petitioner in the District Court in the instant case that the mental cоndition he now alleges is precisely the same as the impairment that he claimed
*286
in the state courts. No facts are alleged to indicate that his condition worsened between the time of his trial in the state court and the filing of his first habeas petition. Criminal law presumes that individuals are competent, see
Smith v. Armontrout,
We hold, therefore, that petitioner’s allegation of cause, when considered in the contеxt of the state-court records in his case, is legally insufficient. The District Court was therefore correct in dismissing his second petition fоr writ of habeas corpus, and the judgment is
Affirmed.
Notes
. The Hon. George F. Gunn, Jr., United States District Judge for the Eastern District of Missouri, adopting the report and recommendation of the Hon. Terry X. Adelman, United States Magistrate Judge for the Eastern District of Missouri.
. Garrett was at the time serving a life sentence for another murder for which he had been convicted in 1977.
. Garrett claims he was being treated with Mel-laril and Thorazine. Mellaril is used to treat adults for depression and anxiety. Thorazine is used to control manic depression and some psychotic disorders. Drugs of these types have, in rare instances, been associated with temporary psychosis. See Physicians’ Desk Reference 2269-71, 2523-25 (50th ed. 1996).
Garrett claimed in his state post-conviction proceeding that he had been taking Mellaril and Thorazine at the -time of his trial. His trial lawyer, hоwever, noted that Garrett appeared perfectly competent when the two conferred pri- or to and during trial. As no' question arose about his competency to stand trial, no pretrial .motion for a mental examination was made. See
Garrett v. State,
